项目摘要

Rehabilitation is very important in preventing an increase of bedridden patients and improving their impairments. Information on the joint moment or muscle action of patients is very useful for doctor or PT to judge what kind of rehabilitation menu is optimum for each patient. The integration of three dimensional motion measurement with multi-camera system and ground reaction measurement with forte plate has been widely used. They apply inverse dynamics to estimate joint moment . However such a method needs sizable work space and it is very expensive for daily rehabilitation.In this research project, a new wearable 3-dimentinal ground reaction force sensor and wearable motion sensor are developed. A parallel type 6-axial load sell, a 3-axial load cell and a motion sensor are mounted in the shoes of patient which is the wearable ground reaction sensor system. Reaction force in local coordinate is transformed to the rectangular coordinate. By using this new wearable reaction force sensor and wearable motion sensor attached to the human lower limb, estimation method of joint moment of human lower limb is developed. Gait analysis is carried out and experimental results of the proposed methods on ground reaction force and joint moment of the lower limb compare well with those by using the conventional method.

康复治疗对防止卧床病人的增加和改善他们的损伤是非常重要的。关于患者的关节力矩或肌肉动作的信息对于医生或PT判断什么样的康复菜单对每个患者是最佳的非常有用。多摄像机三维运动测量与平板法地面反力测量相结合的方法得到了广泛的应用。他们应用逆动力学来估计关节力矩。然而，这种方法需要相当大的工作空间，并且用于日常康复非常昂贵。本研究项目开发了一种新型的可穿戴三维地面反力传感器和可穿戴运动传感器。将并联式六轴测力传感器、三轴测力传感器和运动传感器安装在患者的鞋内，构成可穿戴式地面反力传感器系统。将局部坐标系下的反力转化为直角坐标系下的反力。利用这种新型的可穿戴反力传感器和附着在人体下肢上的可穿戴运动传感器，提出了人体下肢关节力矩的估计方法。对步态进行了分析，实验结果表明，所提出的方法对地面反力和下肢关节力矩的测量结果与传统方法的测量结果吻合较好。
